Too true. Messaging that is relevant to both technical people ("devops") and business (management, procurement, etc) is a hard problem to solve, though!

There seems to be a marketing tendency to either gloss over the technical ideas behind a product, or make technical details front-and-center and leave anyone less than 100% technical searching for a product that they can grok.

This is something we're struggling with right now: our basic messaging for Userify (ssh key management), which is actually a fairly simple and sane product, has gotten a bit out of hand as well: our support team is fielding frequent questions like, "what does each edition do." We've got to get on top of that and get some comparison matrices or something up. Applauding the OP for a nice, clean landing page that conveys most of the relevant details, but as you point out, the Github readme is far better. There's a lesson in there somewhere.
